摘要

研究了镍铬铝复合粉末中的铝浓度对镍铬铝梯度涂层结构的影响。以 NiCr-Al 为基材的梯度涂层是通过引爆喷涂获得的，喷涂过程中筒内乙炔-氧气混合气体的填充量从 50% 逐步减少到 25%。对不同铝浓度下涂层的微观结构进行了分析：15%、20% 和 30%。通过调整混合粉末中的铝浓度，我们实现了涂层的梯度形成。研究结果表明，梯度涂层的相组成受到铝质量百分比的显著影响。研究结果表明，80%镍铬和 20% 铝的粉末成分可生产出具有良好梯度结构的镍铬铝涂层。

Impact of aluminum content upon the microstructure of Ni-Cr-Al gradient coatings

Studied the aluminium concentration in the composite powder NiCr-Al influences the structure of NiCr-Al gradient coatings. Gradient coatings based on NiCr-Al were obtained by detonation spraying, with a phased reduction in the barrel filling volume with acetylene-oxygen gas mixture from 50% to 25%. The coatings' microstructure was analyzed across different aluminum concentrations: 15%, 20%, and 30%. By adjusting the aluminum concentration in the powder mix, we achieved coatings with a gradient formation. The findings indicated that the phase composition of the gradient coating is significantly influenced by the Al mass percentage. The findings suggest a powder composition of 80%NiCr and 20%Al to produce NiCr-Al coatings with a good gradient structure.
